The 'Dundee' sequel is possibly just an elaborate Chris Hemsworth Super Bowl stunt

Australia's most famous film franchise might not be returning to the big screen, after all.

The internet was sent into a frenzy this week with the release of a teaser trailer for the mysterious new project, Dundee: The Son of a Legend Returns Home. The clip, which came without any prior buzz or promotion, appeared to tease the latest instalment of the popular Crocodile Dundee films from the 1980s that originally starred Paul Hogan.

And in a second trailer dropped this week, Chris Hemsworth plays Wally Jr, the son of Mick's business partner Walter "Wally" Reilly. According to People, Hogan, 78, is also set to reprise his role as the iconic bushman Mick Dundee.

The promo clip states the movie will be released in Summer 2018 (unclear which hemisphere's summer they mean). But some film aficionados have speculated that it's not actually a movie, but instead a stunt leading up to a memorable ad during the NFL's Super Bowl on February 4.

As The Daily Telegraphpointed out, many think Hemsworth, a Tourism Australia ambassador, has been tapped to sell Australia to the masses in the way Hogan did with his "Shrimp on the Barbie" campaign in the 1980s.

And people on Twitter had a ~thoughts~ about it.

Additionally, IMDB lists Dundee as completed, although Hemsworth only recently wrapped filming on the untitled Avengers 4 film. McBride recently worked on the 1969 comedy Zeroville with James Franco.

It's also worth mentioning that Dundee's director, Steve Rogers, is actually an advertising executive (per the The Daily Telegraph), which would further point to the project being an elaborate advertisement for Australian tourism.

In teaser trailer, Hemsworth's Wally Jr. holds a sign that reads "Dundee," while waiting patiently to pick up an unknown visitor in the outback. A dusty passenger bus halts before him abruptly, and out hops gruff American Brian Dundee (McBride): Mick's long lost son.

"Danny McBride and I are good mates, we’ve crossed paths a few times in LA, and I knew he would be a great fit for the role," Hemsworth told People on January 23. "The comedic element he brings to the shoot is a huge advantage to the project and a lot of fun on-set."

While the project's validity remains unclear, Hogan himself did reveal that he's excited to bring Dundee back for a new generation of fans.

"Crocodile Dundee is a film that has stood the test of time," Hogan told People. "I’m excited to introduce the new Crocodile Dundee to the world and look forward to sharing more news about those involved very soon."
